Drilling in wood or metal
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece.
There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
NOTICE:
Never use “rotation with hammering”
when the drill chuck is installed on the tool.
The
drill chuck may be damaged.
Also, the drill chuck will come off when reversing the
tool.
NOTICE:
Pressing excessively on the tool will
not speed up the drilling.
In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
Set the action mode changing knob to the symbol.
Attach the chuck adapter to a keyless drill chuck to
which 1/2"-20 size screw can be installed, and then
install them to the tool. When installing it, refer to the
section “Installing or removing drill bit”.
